Your Retirement Number Doesn't Mean Much Without a Lifestyle Plan

I've had thousands of conversations about retirement over my career. And I can tell you the single biggest mistake I see — more than any specific investment decision, more than any account choice — is when people plan their finances without ever truly planning their lifestyle.

They'll have a number in their head. A million dollars. Two million. Whatever the figure is, they're pointed at it. But ask them what they're actually going to do in retirement, and what that's going to cost, and things get vague fast.

That vagueness is expensive.

The Question That Changes the Calculation

Here's the question I ask every client before we talk about a single investment or account: What does your retirement actually look like?

Not in abstract terms. In real terms. Where do you live? Do you stay put or do you move — and if you move, where? Do you travel, and how often? What does your housing cost in retirement versus now? Are you still supporting adult children? Do you have aging parents you might be helping financially?

These questions feel personal because they are. But they're also financial questions. Every answer has a dollar value attached to it.

Retirement Spending Is Not What Most People Expect

There's a common assumption that you'll spend less in retirement than you do while working. And for some people, that's true — particularly in the later years.

But the early years of retirement? For people who retire healthy and active in their early-to-mid 60s, spending often goes up — at least initially. Travel that you put off for decades. Home projects you never had time for. A second home or an RV. The hobbies and experiences that your career kept on the back burner.

I've seen couples who were living on $8,000 a month while working discover that their retirement costs them $10,000 or $11,000 a month — because for the first time in their adult lives, they have the time to actually spend money on things they enjoy.

None of that is wrong. But you need to know that's what your retirement looks like before you can evaluate whether you're financially ready for it.

The Three Phases of Retirement Spending

One framework I find useful: thinking about retirement in three phases, each with a different spending profile.

The Go-Go Years (roughly ages 60–75)

Health is usually good. Energy is high. This is the active travel phase, the bucket list phase. Spending tends to be at its highest. Your income plan needs to support a full, active lifestyle during this window.

The Slow-Go Years (roughly ages 75–85)

Activity levels typically moderate. Long international trips may become less frequent. Discretionary spending often decreases. But healthcare costs start increasing — and that can offset some of the savings.

The No-Go Years (roughly ages 85+)

Mobility and activity are more limited. Healthcare and possibly long-term care become the dominant expenses. Discretionary spending is low, but care costs can be very high.

Understanding this arc doesn't mean you can predict exactly how your retirement will unfold. But it helps you build an income plan that's calibrated to reality rather than one-size-fits-all averages.

When the Lifestyle Plan and the Financial Plan Don't Match

This is the most important part of the conversation — and the one most people avoid.

Sometimes when I map out someone's desired retirement lifestyle against their current financial picture, the numbers don't sync. There's a gap. Their vision costs more than their plan can support.

When that happens, there are really only a few levers to pull: work a bit longer, spend a bit less in retirement, save more aggressively between now and retirement, or adjust the lifestyle vision to be more realistic.

None of those conversations are fun. But having them now — while you have time to make adjustments — is infinitely better than discovering the gap after you've already retired.

I've also seen the reverse: people who have more than enough and don't know it. People holding back on travel and experiences because they're afraid of running out — when the numbers show they have decades of runway. Knowing you can afford your retirement is just as valuable as knowing you can't.

Where to Start

Start with a written lifestyle plan. Not a spreadsheet — a description. Write out what a typical month in retirement looks like. Where you live. What you do. What you spend money on. What you no longer spend money on.

Then translate that into monthly numbers as best you can. Housing, food, transportation, travel, healthcare, entertainment, giving — whatever matters in your life. Get to a number that represents what your retirement lifestyle actually costs per month.

Then stack that against your projected income sources. Social Security. Pension, if you have one. Portfolio distributions. Any other income. See if the math works.

If you've never done that exercise, you might be surprised — in either direction. Either way, you need to know.
